Question

The radiant energy is stored in a form of chemical energy in
A. NADP
B. Stored food
C. RNA
D. DNA

Answer 1

Hint: The change of radiant energy to chemical energy is called photosynthesis. Green plants trap solar energy and synthesize sugar during photosynthesis. Thus, the light energy present in photons is transformed into chemical energy, which is trapped in the sugar molecules' bonds.

Complete answer:
Photosynthesis is the mechanism plants and some algae use chloroplasts — the energy factories contained in plant cells — to transform light energy to chemical energy stored as sugar. For photosynthesis to work, plants require chloroplast, carbon dioxide and water. In photosynthesis, energy stored starts the energy flow and carbon down the food chain. The photosynthetic reaction involves the conversion of radiant energy from the sunlight in the presence of water and carbon dioxide to chemical energy which is stored as oxygen and glucose (sugar).
$6{{H}_{2}}O+6C{{O}_{2}}+sunlight\to {{C}_{6}}{{H}_{12}}{{O}_{6}}+6{{O}_{2}}$
What is meant by this chemical equation is that photosynthesis combines light energy with six carbon dioxide molecules and six water molecules to produce six oxygen molecules and one sugar molecule. Plants use light energy to begin the process of photosynthesis and to fuel energy storage in sugars. Thus, we can say, radiant energy is stored as chemical energy in food.

The correct answer is option (B).

Additional Information:
Photosynthesis is divided into two primary phases: light response and dark response. The light reaction converts light energy into adenosine triphosphate (ATP), the energy currency of all life, and Nicotinamide adenine dinucleotide phosphate, both of which become energy-carrier molecules needed for the dark stage of photosynthesis. This step occurs in the thylakoid membrane. The dark reaction employs ATP and NADPH created in the light reaction to transform carbon dioxide into sugar. This phase happens within the plant's stoma in the dark. Carbon dioxide combined with ribulose bisphosphate and ATP helps convert the product of stage one into sugar.

Note:
ATP is an essential component in the process of photosynthesis. Biologists consider it the currency of life because it is the cell's readily available source of energy to do just about anything, from moving muscles to enabling respiration.
